PNEUMATIC DUSTING AND SWEEIPING- APPLIANCE.

I Specification of Letters Patent.

Patented Feb. 16,1909.

Application filed March- 8, 1907. Serial No. 361,332.

To all whom it may concern: Be it known that I, CHARLES JAMES HAR- vEY,a subject of the British King, residing at 9 Church street, Kiddermi-nster, Worcester, '5 En land, have invented certain new and useful Improvements in Pneumatic Dusting and Sweeping Appliances; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will '10 enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in pneumatic dusting and swee ing appliances, and has for its. object to pro use a slmple and inex ensive machine for the purpose which shall e portable and easily operated by one person only, so as to be particularly suited to the requirements of small households, shops, and ofiices.

Heretofore pneumatic dusting appliances for various purposes have been provided that were operated by pumps or bellows, but so far as am aware they were not provided with a bellows ada ted to rest on the surface to be cleaned or otlier support, and to be actuated by the foot of the operator, while his hands were left free to manipulate the suction nozzle to seek out obscure and inaccessible spots, all as will appear below.

My apparatus consists essentially of a single acting exhaust bellows actuatedbya pedal and rovided with a dust collecting nozzle and fibxible connecting tube with suitable in-' let and outlet valves, and carrying a dust re- 3 taining device; all as hereinafter described with reference to the accompanying drawings in which Figure 1, represents an elevational view partly in section-of my apparatus and Fig. 2,

4 a longitudinal sectional view of my invention.

In carrying the same into effect I make use of a sin le foot bellows, a, of the ordinary hinged shape, the pedal, 1), of which is fixed at a slight angle to, and forms an extension of,

the upper bellows board. This board is supported sufficiently oil the ground by the bracket; 0, between the. arms of which it is pivoted. The said bracket, 0, is of a suitable height to allow for the full expansion of the bellows and the base may be sufficiently broad toenable it to-stand upright on the ground, or any convenient means may be employed for fixing it in an upright position.

lhe bottom bellows board is extended to a point sufficiently beyond the rear of the tion.

and t e pedal, 1;, and is of 'sufiicient strength to normally keep the bellows closedi use a dust retaining bag or screen, 0, which 7 may beextended over the air exit or inlet or elsewhere in the passage of the air current providing it fulfils its function of filtering the dust from the air; but I prefer it to be carried inside the bellows (as shown) and inserted through an aperture in the upper board, the mouthof the bag, e, being preferably extended round the ed e of the aperture and closed by an air tight lid, f, or the like.

A dust removing or collecting nozzle, g, is in connection with the bellows by means of a suitable length of tubing,f h, as usually employed. The dust may be collected within the bellows, a, but I refer to collect it Within the bag, e, aforesak for convenience of removal.

The inlet valve 2' should be of soft collapsible material such as rubber, calico, or the like, to prevent any back rush of dust, and the exit valve 7' or valves may be made of any material allowing easy action.

The operation of my device is as follows:

The bellows and its bracket 0 is placed on the floor or ground, and pressure a lied to the pedal 12 by means of the foot. l iis is made the more easy on account of the pedal 1) being supported oil the ground by means of the bracket 0, and b reason of the said bracket being of a suitable hei ht to allow for the full expansion of the bel ows, asstated above. The power being a plied through the foot, and the bracket 0 being of suitable dimensions to steady the bellows, the hands of the operator are free to mani ulate the nozzle g, as also stated above, am when the air and dust is sucked into the nozzle, it is delivered to the bag e,- which allows the air to escape, but retains the dust. On raising the foot, the pedal 12 is returned by the spring (1.

It will thus be seen that byemploying a foot-operated bellows suitably supported by the bracket 0, I am enabled to operate the same by the foot alone and thereb leave the hands tree to manipulate the nozzlb and seek out any otherwise naccessible places. This I consider an important feature of my invenanying drawing a nozzle, 1, e for use in dusting a carpet but nozzles of various shapes or de- In the accom is shown suit-ab or floor,

I employ no separate dust collector, but I signs may be connected'to the tube, h, to suit difierent requirements such as for dusting shelves, furniture, and the like.

Claim. y

' The combination in a pneumatic dusting and sweeping a pliance, of the bellows a, havi its top oard extended to form a pedal and its lower board extended to form a sup ort; the bracket stand a pivotally attache to the top board of the bellows a the compression spring (1, between the top and lower board extensions; the dust retainin bag e, inserted within the bellows a, throng an aperture in the upper board and having its mouth extended around the ed e of the 5 aperture and closed by the air tight 'd the dust collecting nozzle 9, and connecting tube It, with suitable inlet and outlet valves); and j, substantially as shown and described.

In testimony whereof, I afiix my signature 2 in presence of two Witnesses.
